BOILER STRUCTURE.

Original application filed Kay 31, 1923, Serial No. 642,427. Divided and this application filed June 25,

1924. Serial No. 722,226.

This application is a division of my application Serial No. 642,427 filed May 31, 1923, and relates to details of boiler construction and aims to provide a structure adapted to form either a boiler wall or a tube assembly.

An embodiment of the invention is illustrated in the accompanying drawings in which-- Fig. 1 is a sectional perspective; and

broken away.

Fig. 3 illustrates a modification.

In the drawings, I show a plurality of practically square boiler tubes 102 connected to a header section 104, the tubes being spaced apart by T-bars 106 which are welded or otherwise secured between the adjacent tubes. These T-bars are adapted to serve as baffle walls between the different boiler 2 tubes. And they ar'e/ffiade in short lengths similar upri ht at theother side of the structure and Wlll therefore close the'space between the adjacent tubes 102. The boiler tubes 102 may be formed by butt welding' Fig. 2 is a side elevation with portions 'two channel sections along their 0 posed While I have described the specific embodiment of the invention herein illustrated, it is not to be construed'that I am limited thereto as various modifications may be made by those skilled in the art without de- 40 parting from the invention as defined in the appended claims.

What I claim is 7 I 1. .A boiler including a header of substantially rectangular cross-section, a multiplicity of substantially rectangular boiler tubes communicating therewith and a'series of T- bars secured between the adjacent tubes and extending longitudinally of the tubes, said bars being spaced apart to form openings at intervals between the tubes. 2. A boiler wall including a headerhaving connected therewith a tube structure comprising a plurality of hollow flat sided tubes and bars extendin longitudinally of the tubes and closing the spaces between adjacent tubes, each bar having at least oneflange and web the flat surface of said flange engaging the flat surface of. one tube and a thin edge of said web engaging the flat surface of an adjacent tube.

In witness whereof, I have hereunto signed my name. .i. a
